Artificial stone mainly includes resin artificial stone, composite artificial stone and cement artificial stone. The details are as follows: 1. Resin-based artificial stone. Resin-based artificial stone uses unsaturated polyester resin as a cementing agent, mixed with natural marble rubble, quartz sand, calcite, stone powder or other inorganic fillers in a certain proportion, and adds catalysts and curing agents. , pigments and other artificial stone agents, and then mixed, stirred, solidified, demoulded, dried, and surface polished. Products using unsaturated polyester have good gloss, bright and rich colors, strong processability, and good decorative effects. This resin has low viscosity, is easy to mold, and cures at room temperature. 2. Composite artificial stone The binders used in composite artificial stone include both inorganic materials and organic polymer materials. The manufacturing process is: first use cement and stone powder to make a green body of cement mortar, and then immerse the green body in organic monomers to polymerize under certain conditions. For the board, the bottom layer is made of inorganic materials with stable performance and low price, and the surface layer is made of polyester and marble powder. Composite artificial stone products are low in cost, but the polyester surface is prone to peeling or cracking due to temperature differences. 3. Cement-based artificial stone Cement-based artificial stone is an artificial stone made of various cements as cementing materials, sand and natural gravel particles as coarse and fine aggregates, and is made by batching, stirring, autoclaving, grinding and polishing. During the preparation process, colored cement stones can be made by mixing human pigments. Cement-based stone is easy and cheap to produce, but has poor decorative properties. Terrazzo and various flower step tiles belong to this category.
